Abstract: To reliably and consistently detect desirable sounds, a system detects the presence of wind noise based on the power levels of audio signals. A first transducer detects sound originating from a first direction and a second transducer detects sound originating from a second direction. The power levels of the sound are compared. When the power level of the sound received from the second transducer is less than the power level of the sound received from the first transducer by a predetermined value, wind noise may be present. A signal processor may generate an output from one or a combination of the audio signals, based on a wind noise detection.

Abstract: The invention relates to a system and method for generating realistic network traffic by replaying captured network traffic using parallelized streams of subtraces. In accordance with one method of the invention, a captured trace of network traffic from a network link is provided. The captured trace is split into a number of subtraces. The subtraces are replayed and then recombined into a recombined trace, wherein the timing of packets in the recombined trace approximates the timing of packets in the captured trace.

Abstract: A method, system and a computer-readable media for automatically detecting that a malfunction affecting message withdrawal from a queue is present is described. In one embodiment, the malfunction is detected by evaluating the number of messages that enter and leave a queue during a period of time. For example, if the messages entering the queue do not equal the messages leaving the queue a malfunction may be present. In one embodiment, queue-performance indicator is calculated based on the number of messages leaving and entering the queue. If the queue-performance indicator is outside of the normal-operating range an alarm is generated and sent to a designated responder who can fix malfunctions associated with the queue.

Abstract: Computer implemented methods and systems are provided for web log filtering. A uniform resource locator (URL) is identified for a resource requested by an identified device.

The stored URL is categorized based on either the stored URL or an included domain name, depending on whether the included domain name matches any of the list of domain names that are associated with multiple categories. A count is incremented in a web log category associated with the identified device based on the categorized stored URL.

Abstract: A method of locating a sound source based on sound received at an array of microphones comprises the steps of determining a correlation function of signals provided by microphones of the array and establishing a direction in which the sound source is located based on at least one eigenvector of a matrix having matrix elements which are determined based on the correlation function. The correlation function has first and second frequency components associated with a first and second frequency band, respectively. The first frequency component is determined based on signals from microphones having a first distance, and the second frequency component is determined based on signals from microphones having a second distance different from the first distance.

Abstract: Cellular telephone handsets often include electronic or software coding that “locks” them to a specific wireless network. Provided herein, is a method for provisioning locked handsets by unlocking them from their established network and relocking them on a new cellular network. The handset is connected in communication with the control process, identified, and provisioned. The method allows for provisioning of multiple models and brands to be provisioned from different carriers and to different carriers. It further allows multiple handsets to be provisioned simultaneously. During the process, the handset may be sensitivity tested. Further, the identification portion of the method can be used in conjunction with phone support tools beyond the provisioning process.

Abstract: One embodiment is a method for precoding data for transmission in a discrete multi-tone (DMT) system to cancel self-induced far end crosstalk (self-FEXT). The method comprises learning, by the system, characteristics associated with a plurality of N users within a digital subscriber line (xDSL) system to determine an initial off-diagonal multiple input multiple output (MIMO) precoder (ODMP) for a given tone frequency and converging towards an ODMP from the initial ODMP to cancel self-FEXT for the plurality of N users, wherein the ODMP is represented as a zero diagonal matrix containing only off-diagonal terms.

Caller identification information for the voice mail message may thereby be provided as a notification that the voice mail message was received at the voice mail server. Related methods, systems and devices are disclosed.

Abstract: An echo reduction system includes a signal analysis filter that converts an input into sub-band signals. A signal down-sampling circuit down-samples the sub-band signals at a first down-sampling rate. An echo analysis filter converts a loudspeaker signal into echo sub-band signal that are further processed by an echo down-sampling circuit. The circuit down-samples the echo sub-band signals at a second down-sampling rate to generate down-sampled echo sub-band signals. An echo compensation filter folds the down-sampled echo sub-band signals with an estimated impulse response of a loudspeaker-room-input system. A second echo down-sampling circuit down-samples the folded down-sampled echo sub-band signals at a third down-sampling rate to generate estimated echo sub-band signals. The first down-sampling rate is equal to the product of the second and third down-sampling rates.
